Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fluorescent tubes or high-pressure lamps are used for irradiation, then the irradiation function is achieved, but the housing parts become large and consume a lot of space
Solution Approach 1:
The patent changes the fundamental parameter of the light source from traditional fluorescent tubes or high-pressure lamps to LEDs (light-emitting diodes). This parameter change enables significantly reduced power consumption while maintaining effective irradiation output, directly resolving the contradiction between energy efficiency and device size. The LED technology allows the same irradiation function to be achieved with much smaller components.
2Adaptability or versatility
If traditional irradiation devices are used, then irradiation is provided, but customization for different users and body parts is not possible, leading to varied irradiation results
Solution Approach 1:
The patent divides the irradiation device into multiple independently controllable LED modules, each capable of being adjusted separately. This segmentation allows different irradiation parameters (intensity, wavelength, duration) to be applied to different body parts simultaneously, enabling full customization for individual users without requiring complex mechanical adjustments. Each LED module can be controlled independently through a microcontroller.
Solution Approach 2:
The patent implements dynamic control of irradiation parameters through software, allowing real-time adjustment of irradiation intensity and spectrum based on user needs and skin sensitivity. The microcontroller enables dynamic modification of irradiation protocols during treatment, adapting to individual user requirements without mechanical complexity.
3Productivity
If high-power irradiation is used to achieve better results, then irradiation effectiveness improves, but risk of burns and harmful effects increases
Solution Approach 1:
The patent incorporates feedback control through sensors that monitor irradiation output and user response in real-time. The microcontroller receives feedback from these sensors and dynamically adjusts LED power output to maintain optimal irradiation levels, preventing overheating and burn risks while maximizing tanning effectiveness. This closed-loop control ensures safety without compromising productivity.
